Full Title

Full titles differ between systems:

IPC:

Optical elements characterised by the material of which they are made; Optical coatings for optical elements > Optical coatings produced by application to, or surface treatment of, optical elements > Coatings for keeping optical surfaces clean, e.g. hydrophobic or photo-catalytic films

CPC:

Optical elements characterised by the material of which they are made; Optical coatings for optical elements > Optical coatings produced by application to, or surface treatment of, optical elements (G02B1/08 takes precedence) > Coatings for keeping optical surfaces clean, e.g. hydrophobic or photo-catalytic films (G02B1/16 takes precedence)

No child classifications to compare. This is a leaf node in both IPC and CPC.
